AWS CodeDeploy AfterInstall script is being run from code-deploy agent dir
提问by matewilk
I'm trying to run AfterInstall script in AWS code deploy, but it is being run from the /opt/codedeploy-agent/ dir instead of my app directory.
我正在尝试在 AWS 代码部署中运行 AfterInstall 脚本，但它是从 /opt/codedeploy-agent/ 目录而不是我的应用程序目录运行的。
This is how appspec.yml file looks like:
这是 appspec.yml 文件的样子：
version: 0.0
os: linux
files:
- source: /
destination: /tmp/epub
hooks:
AfterInstall:
- location: server/install-packages.sh
runas: root
As you can see it's a basic example.
如您所见，这是一个基本示例。
Now, the bash script looks like this:
现在，bash 脚本如下所示：
#!/bin/bash
npm install
I just want to npm install and that's it.
我只想 npm install 就是这样。
Unfortunately I'm getting the error:
不幸的是我收到错误：

I was trying different appspec.yml configs like adding runas or adding "/" at the beginning of the location path. All the time it's trying to run from /opt/codedeoploy-agent/ directory.
我正在尝试不同的 appspec.yml 配置，例如在位置路径的开头添加 runas 或添加“/”。它一直试图从 /opt/codedeoploy-agent/ 目录运行。
In desperation, I've set absolute path to the script, but then I got :
无奈之下，我已经为脚本设置了绝对路径，但后来我得到了：
Script does not exist at specified location: /tmp/epub/server/install-packages.sh
It's really annoying as I'm doing everything according to docs, but probably I'm missing something very very small !
这真的很烦人，因为我按照文档做所有事情，但可能我错过了一些非常非常小的东西！
Thanks
谢谢

Ok,
好的，
So I've found out, that codedeoloy-agent is running AfterInstall (and probably all the other steps) from the temporary directory created by the agent on deploy instance, so in my case I had to modify the bash script by cd-ing to the proper directory:
所以我发现，codedeoloy-agent 正在从代理在部署实例上创建的临时目录运行 AfterInstall（可能还有所有其他步骤），所以在我的情况下，我不得不通过 cd-ing 修改 bash 脚本正确的目录：
#!/bin/bash
cd /tmp/epub/server/
npm install
